This Arduino project solves a practical household problem: It was difficult to know when the water in the shower had reached a comfortable temperature and when to boost the water.

Abstract: This brief presents a 0.5-8 GHz CMOS RF receiver front-end (RxFE) tailored for cognitive radio (CR) and digital phased array (DPA) applications. The RxFE comprises a wideband mixer with ...

Abstract: Rydberg-atom quantum receivers (RAQRs) enable ultra-sensitive RF detection by transducing incident fields into the optical domain with minimal quantum noise. This letter addresses the ...

Each jamming mode is implemented as a distinct modulation scheme and data pattern. The app generates these patterns and transmits them over the RF link to disrupt legitimate signals in the selected ...
